I've searched and haven't found what I'm looking for so pardon me if it's been discussed somewhere already.

I've read countless times about how the audio quality when using the dongle is far superior to using the headphone jack. My question is, if I use a 3.5mm plug coming out of the dongle and plug the other 3.5mm end into my aux input on my car radio, will I hear the same improvement as if I used the 3.5mm to RCA inputs?
